Optical tracking is widely used in robotics applications such as unmanned aerial vehicle (UAV) localization. Unfortunately, such systems require many cameras and are, consequently, expensive. In this paper, we propose an approach to considerably increase the optical tracking volume without adding cameras. First, when the target becomes no longer visible by at least two cameras we propose a single-view...
In this paper we introduce a novel approach for stereoscopic rendering of virtual environments with a wide Field-of-View (FoV) up to 360°. Handling such a wide FoV implies the use of non-planar projections and generates specific problems such as for rasterization and clipping of primitives. We propose a novel pre-clip stage specifically adapted to geometric approaches for which problems occur with...
Typical field-of-view (fov) of visual feedback in virtual reality applications is generally limited. In some cases, e.g. in videogames, the provided fov can be artificially increased, using simple perspective projection methods. In this paper, we design and evaluate different visualization techniques, inspired by the cartography domain, for navigating in virtual environments (VE) with a 360° horizontal...
